Title

dried seeds

Problem Scenario

how mch water ar in seeds

Broad Question

will the size of the seed effect how much water it has in it

Specific Question

will drying effect how much the seeds weigh

Hypothesis

i think that the more water in the seeds the more they weigh. if you dry the seeds all the way the will weigh less.

Graph of Hypothesis

Variables

Independent Variable:the dryness of seeds

Dependent Variable:the weight of seeds

Variables That Need To Be Controlled:

the temperature
how long you dry the fruit

General Plan

I will get a knife and chop the apples in half (in fourths if I need to). When the apple is chopped then I will take a tooth pick (or any utensil I use) and take out the seeds and wash them off. Once they are all clean then I will weigh them in a cup (of course I will zero the cup before adding the seeds) before drying them. Once they dry I will weigh them again write down the difference between the non dried and the dried seeds to see how much water is in seeds. Once I have that data then I will input the data into the MWVScienceFair website (this site you are on probably) so that I can have this page complete. After This wiki space done I will work on the poster for the science fair which will becoming soon at that time. Then the poster will be done & I will just have to wait for the science fair.

Potential Problems And Solutions

problem: having chunks of on the seeds
solution:clean them

Safety Or Environmental Concerns

safety concern: I might get hurt with a knife when i cut the fruit
environmental concern: There truly none

Results

As you can see from the graph above orange seeds have more water in them then apple seeds. orange seeds are 27% water and apple seeds are 9% water. In my hypothesis I stated that the bigger the seed (the orange seeds are bigger by comparison) the more it will weigh for it will contain more water then smaller seeds ( the apple seeds was smaller by comparison ).I had nine different trials and then I averaged them all ( all the orange seeds in one average and all the apple seeds in one average ) and turned them into percent so I could transform the info into a graph. Orange is orange, Apple is green (because I used granny smith apples which are green).
Conclusion
My hypothesis is the more water in the seeds the more they weigh. if you dry the seeds all the way the will weigh less. And I accept my hypothesis because orange seeds are bigger then apple seeds and they contained more water.

Discussion

If you dry a seed it will effect its mass. My data showed that orange seeds contain more water then apple seeds. since they have a bigger size then the apple seeds my hypothesis was correct. My hypothesis was that the bigger the seed the more water it will contain. It might be wrong though since I only did 2 seeds, if you want more data you could add a whole bunch of seeds and see if my hypothesis is still correct.

Benefit to Community and/or Science

Mine does not effect the community and could not be of use to anybody. exept for gardeners maybe

Abstract

Well first I started doing wiki spaces until I needed to do my experiment ( they were title, Problem scenario, broad question, specific question, Hypothesis, & so so & so on until data table). Then I took 9 apple seeds and 9 orange seeds weighed them. Next I dried them for about a week then I weighed them again. Then I did allot of math then made a graph for my experiment.. Next I Finished my wiki spaces until I got to Abstract then i started to write it until I got to where I am now.
